  • Achieving High and Consistent Rendering Performance of Java AWT/Swing on Multiple Platforms
    SOFTWARE—PRACTICE AND EXPERIENCE Softw. Pract. Exper. 2009; 39:701–736 Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/spe.920 Achieving high and consistent rendering performance of Java AWT/Swing on multiple platforms Yi-Hsien Wang and I-Chen Wu∗,† Department of Computer Science, National Chiao Tung University, Hsinchu, Taiwan SUMMARY Wang et al. (Softw. Pract. Exper. 2007; 37(7):727–745) observed a phenomenon of performance incon- sistency in the graphics of Java Abstract Window Toolkit (AWT)/Swing among different Java runtime environments (JREs) on Windows XP. This phenomenon makes it difficult to predict the performance of Java game applications. Therefore, they proposed a portable AWT/Swing architecture, called CYC Window Toolkit (CWT), to provide programmers with high and consistent rendering performance for Java game development among different JREs. They implemented a DirectX version to demonstrate the feasibility of the architecture. This paper extends the above research to other environments in two aspects. First, we evaluate the rendering performance of the original Java AWT with different combi- nations of JREs, image application programming interfaces, system properties and operating systems (OSs), including Windows XP, Windows Vista, Fedora and Mac OS X. The evaluation results indicate that the performance inconsistency of Java AWT also exists among the four OSs, even if the same hardware configuration is used. Second, we design an OpenGL version of CWT, named CWT-GL, to take advantage of modern 3D graphics cards, and compare the rendering performance of CWT with Java AWT/Swing. The results show that CWT-GL achieves more consistent and higher rendering performance in JREs 1.4 to 1.6 on the four OSs.

  • Interpretive Opengl for Computer Graphics Bo Chen, Harry H
    ARTICLE IN PRESS Computers & Graphics 29 (2005) 331–339 www.elsevier.com/locate/cag Technical section Interpretive OpenGL for computer graphics Bo Chen, Harry H. Chengà Integration Engineering Laboratory, Department of Mechanical and Aeronautical Engineering, University of California, Davis, CA 95616, USA Abstract OpenGL is the industry-leading, cross-platform graphics application programming interface (API), and the only major API with support for virtually all operating systems. Many languages, such as Fortran, Java, Tcl/Tk, and Python, have OpenGL bindings to take advantage ofOpenGL visualization power. In this article, we present Ch OpenGL Toolkit, a truly platform-independent Ch binding to OpenGL for computer graphics. Ch is an embeddable C/ C++ interpreter for cross-platform scripting, shell programming, numerical computing, and embedded scripting. Ch extends C with salient numerical and plotting features. Like some mathematical software packages, such as MATLAB, Ch has built-in support for two and three-dimensional graphical plotting, computational arrays for vector and matrix computation, and linear system analysis with advanced numerical analysis functions based on LAPACK. Ch OpenGL Toolkit allows OpenGL application developers to write applications in a cross-platform environment, and all of the OpenGL application source code can readily run on different platforms without compilation and linking processes. In addition, the syntax ofCh OpenGL Toolkit is identical to C interfaceto OpenGL. Ch OpenGL Toolkit saves OpenGL programmers’ energies for solving problems without struggling with mastering new language syntax. Ch OpenGL Toolkit is embeddable. Embedded Ch OpenGL graphics engine enables graphical application developers or users to dynamically generate and manipulate graphics at run-time.

  • A Portable AWT/Swing Architecture for Java Game Development
    SOFTWARE—PRACTICE AND EXPERIENCE Softw. Pract. Exper. 2007; 37:727–745 Published online 2 November 2006 in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/spe.786 A portable AWT/Swing architecture for Java game development Yi-Hsien Wang, I-Chen Wu∗,† and Jyh-Yaw Jiang Department of Computer Science, National Chiao Tung University, Hsinchu, Taiwan SUMMARY Recently, the performance of Java platforms has been greatly improved to satisfy the requirements for game development. However, the rendering performance of Java 1.1, which is still used by about one-third of current Web browser users, is not sufficient for high-profile games. Therefore, practically, Java game developers, especially those who use applets, have to take this into consideration in most environments. In order to solve the above problems, this paper proposes a portable window toolkit architecture called the CYC Window Toolkit (CWT) with the ability to: (1) reach high rendering performance particularly in Java 1.1 applications and applets when using DirectX to render widgets in CWT; (2) support AWT/Swing compatible widgets, so hence the CWT can be easily applied to existing Java games; (3) define a general architecture that supports multiple graphics libraries such as AWT, DirectX and OpenGL, multiple virtual machines such as Java VM and .NET CLR, and multiple operating systems (OSs) such as Microsoft Windows, Mac OS and UNIX-based OSs; (4) provide programmers with one-to-one mapping APIs to directly manipulate DirectX objects and other game-related properties. The CWT has also been applied to an online Java game system to demonstrate the proposed architecture.

  • An Approach to 3D on the Web Using Java Opengl
    НАУЧНИ ТРУДОВЕ НА РУСЕНСКИЯ УНИВЕРСИТЕТ - 2009, том 48, серия 6.1 An Approach to 3D on the Web using Java OpenGL Tzvetomir Vassilev, Stanislav Kostadinov Един подход към 3D в интернет с използване на Java OpenGL: Статията описва един подход за визуализация на тримерни сцени с използване на Java OpenGL и XML. Разгледани са няколко съществуващи технологии и са описани техните предимства и недостатъци. Предложен е формат базиран върху X3D и Open Inventor и е разработено Java приложение за визуализацията му. С негова помощ могат да се създават аплети за визуализация на тримерни обекти. Размерът на приложението е малък и зареждането му става достатъчно бързо. Изисква се на клиетна да е инсталиран единствено Java plugin за съответния браузер. Key words: 3D visualization, OpenGL, XML. INTRODUCTION Web technologies developed very quickly in the recent years and penetrated many different fields in human life. More and more applications require visualization of three- dimensional (3D) objects. Different graphics libraries and packages have been developed, like OpenGL, Direct3D, Open Inventor, etc. However, there is no common standard and format for the visualization and storage of 3D objects on the Web. This paper describes several existing file formats and technologies for the visualization of 3D data on the web, addressing their features and disadvantages. It proposes a new format, based on Open Inventor and XML and describes a web application, based on Java OpenGL (JOGL).
